Important Safety Information
Isocyanate Conditions
Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.
Keep the ISO lube pump reservoir (if installed) filled with Graco Throat Seal Liquid (TSL), Part 206995. The lubricant creates a barrier between the ISO and the atmosphere.
Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.
Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.
Never use solvent on one side if it has been contam- inated from the other side.
Always lubricate threaded parts with ISO pump oil or grease when reassembling.
Keep Components A and B Separate
Foam Resins with 245 fa Blowing Agents
Some foam blowing agents will froth at temperatures above 90°F (33°C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation system.
Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized partic- ulates.
Read material manufacturers warnings and material MSDS to know specific hazards and precautions related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventila- tion in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.
To prevent contact with isocyanates, appropriate per- sonal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.
Some materials may become self-igniting if applied too thickly. Read material manufacturers warnings and material MSDS.

NOTICE
To prevent cross-contamination of the equipments wetted parts, never interchange component A (isocy- anate) and component B (resin) parts.
Methyl Ethyl Ketone Peroxide (MEKP)
MEKP is among the more hazardous materials
found in commercial channels. Proper handling
of the “unstable (reactive)” chemicals presents a
denite challenge to the plastics industry. The highly reactive property which makes MEKP
valuable to the plastics industry in producing the curing reaction of polyester resins and gel-coats also produces the hazards which require great care and caution in its storage, transportation, handling, processing and disposal.
Workers must be thoroughly informed of the hazards
that may result from improper handling of MEKP,
especially in regards to contamination and heat. They must be thoroughly instructed regarding the
proper action to be taken in the storage, use and disposal of MEKP and other hazardous materials
used in the laminating operation.
MEKP is ammable and potentially explosive, as well as potentially damaging to the eyes and
skin.
Read material manufacturer’s warnings and material MSDS to know specic hazards and precautions related to MEKP.
Contaminated MEKP can become explosive.
Prevent contamination of MEKP with other materi-
als, which includes, but is not limited to polyester overspray, polymerization accelerators and promot-
ers, and non-stainless metals. Even small amounts
of contaminates can make MEKP explosive. This re-
action may start slowly, and gradually build-up heat,
which can accelerate until re or an explosion result. This process can take from seconds to days.
Heat applied to MEKP, or heat build-up from con-
tamination reactions can cause it to reach what is
called its Self-Accelerating Decompisition Tempera-
ture (SADT), which can cause re or explosion.
Spills should be promptly removed, so no residues remain. Spillage can heat up to the point of self-
ignition. Dispose in accordance with manufacture’s
recommendation.
Store MEKP in a cool, dry and well-ventilated area
in the original containers away from direct sunlight and away from other chemicals. It is strongly recom­mended that the storage temperature remain below
86° F (30° C). Heat will increase the potential for ex-
plosive decomposition. Refer to NFPA 432. Keep MEKP away from heat, sparks and open ames.
Current catalysts are premixed and do not require any diluents. GlasCraft strongly recommends that dilu­ents not be used. Diluants add to the possibility of con­taminates entering the catalyst system. Never dilute
MEKP with acetone or any solvent since this can pro-
duce an extremely shock-sensitive compound which
can explode.
Use only original equipment or equivalent parts
from GlasCraft in the catalyst system (i.e.: hoses, t-
tings, etc.) because a hazardous chemical reaction
may result between substituted parts and MEKP. To prevent contact with MEKP, appropriate personal
protective equipment, including chemically imperme­able gloves, boots, aprons and goggles are required
for everyone in the work area.
Polyester Resins and Gel-Coats
Spraying materials containing polyester resin and gel-coats creates potentially harmful mist, vapors and
atomized particulates. Prevent inhalation by providing sufcient ventilation and the use of respirators in the work area.
Read the material manufacturer’s warnings and ma-
terial MSDS to know specic hazards and precautions
related to polyester resins and gel-coats. To prevent contact with polyester resins and gel­coats, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons and goggles are required for everyone in the
work area.
Spraying and Lamination Operations
Remove all accumulations of overspray, FRP sand-
ings, etc. from the building as they occur. If this waste is allowed to build up, spillage of catalyst is more likely to start a re. If cleaning solvents are required, read material manufacture’s warnings and material MSDS to know
specic hazards and precautions. (GlasCraft recom-
mends that clean-up solvents be nonammable.)
GlasCraft recommends that you consult OSHA Sections 1910.94, 1910.106, 1910.107 and NFPA No. 33, Chapter 16,17, and NFPA No. 91 for further
guidance.

Overnight Shut Down Procedure
The following steps should be followed for overnight
shutdown:
1. The yellow air valve located where the air enters the machine should be pushed to the “OFF” (closed) position. To do this simply push on the lever protruding out the side of the valve. This will also cause all the system air to bleed out of the system in a matter of a
few seconds thus making the system
incapable of operating.
Step 2 is a precautionary step and should be followed whenever the emergency stop valve is activated to the stop mode. Failure to do so will damage regulators and components when reactivating to the ON position.
2. Turn all system regulators to OFF (counter­ clockwise) position.
Verify that the Catalyst Pressure Relief Line and the Resin Return Line are secured before relieving
catalyst and resin uid pressure.
3. Catalyst pressure in the Slave Pump can be
eliminated by rotating the yellow valve handle
on the Slave Pump 90 degrees to the “ON”
position.
The “ON” position the valve handle is parallel (in line) with the valve body . The “OFF” position the valve handle is perpendicular (across) the valve body.
4. Resin pressure can be eliminated by rotating the yellow handled valve on the bottom of
the uid lter 90 degrees. Place a container
under the bottom of the valve to catch any resin that is ejected from the valve.

Maintenance
Isocyanate Conditions
Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.
Keep the ISO lube pump reservoir (if installed) filled with Graco Throat Seal Liquid (TSL), Part 206995. The lubricant creates a barrier between the ISO and the atmosphere.
Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.
Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.
Never use solvent on one side if it has been contam- inated from the other side.
Always lubricate threaded parts with ISO pump oil or grease when reassembling.
Keep Components A and B Separate
Foam Resins with 245 fa Blowing Agents
Some foam blowing agents will froth at temperatures above 90°F (33°C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation system.
Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized partic- ulates.
Read material manufacturers warnings and material MSDS to know specific hazards and precautions related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventila- tion in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.
To prevent contact with isocyanates, appropriate per- sonal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.
Some materials may become self-igniting if applied too thickly. Read material manufacturers warnings and material MSDS.
The amount of film formation and rate of crystalli- zation varies depending on the blend of ISO, the

Parts Replacement Procedure
Formula Gun
Before performing maintenance on the dispense gun, follow Pressure Relief Procedure.
Notice
Due to the different o-ring materials and lubricants used
in the dispense guns, never submerge or soak any dis­pense gun in any type of solvent. Submerging or soak-
ing any dispense gun will immediately void the gun war­ranty.
1. Read each procedure entirely before beginning and refer to the illustration views as needed.
2. Flush and clean all passages as they become
accessible.
3. Clean all parts before assembly.
4. Replace all O-Rings, Valves and Seals with new parts from the appropriate kit.
5. Inspect all parts for wear or damage and replace as required with new GENUINE GlasCraft REPLACEMENT PARTS from your authorized GlasCraft Distributor.
6. Inspect all threads for wear or damage and
replace as required.
7. Tighten all threaded parts securely, but not excessively, upon assembly.
8. O-rings can fail if subjected to any of the following conditions.
a. Swelling - coming in contact with solvent or oil from compressor. b. Cut - sharp, unlubricated edge in gun head or handle.
c. Sticky - contaminated with oil, water,
solvent, catalyst, resin or gel-coat.
d. Chafng - dry sliding surfaces (needs
lubrication).
9. Lightly lubricate all O-Rings with petroleum jelly.
10. Check all springs for resilience. They should return quickly to their original (new) length.
11. Clean the exterior of the Gun and Hoses with
an appropriate, clean solvent and cloth or brush.
Hose Removal
1. Relieve pressure (See page 14).
2. Remove resin Hose with an 11/16” wrench. (Hold delivery tube with an 11/16” wrench.)
3. Remove catalyst Hose with a 9/16” wrench. (Hold delivery tube with a 9/16” wrench.)
4. Remove solvent hose with a 5/8” wrench. (Hold delivery tube with a 9/16” wrench)
5. Remove trigger air tubing by pushing in on trigger air tting and pulling the tubing out.
6. If optional berglass chopper is being used, remove the chopper air hose with a 11/16” wrench. (Hold the air hose inlet tting with a 9/16” wrench)
Tape a clean polyethylene bag over the end of each Hose to prevent spillage and to keep clean.
